The endosperm in angiosperm develops from______.
Synergids or synergid cells are haploid accessory cells at the micropylar pole of the angiosperm embryo sac; glandular-like cells involved in pollen tube attraction and reception.
Eight nucleate embryo sacs are:
► Megapore is a haploid structure which divides and gives rise to embryo sac which is also called as female gametophyte.
► Eight-nucleate embryo sacs may be:
The endosperm cells in angiosperms are:
In the sixteen-cell stage of the embryo in dicots, the eight protodermal cells show which kind of division?
In the sixteen-cell stage of the embryo in dicots, the eight protodermal cells divide further by anticlinal division to form the embryonic surface layer, while the inner eight cells divide in different planes to form the ground meristem and procambium.
The outermost layer of maize endosperm is known as:
Aleurone is a protein found in protein granules of maturing seeds and tubers. It also describes one of the two major cell types of the endosperm, the aleurone layer. It is the outermost layer of the endosperm.
Structure of Maize Seed:
In Double fertilisation:
Endosperm is consumed by a developing embryo in the seed of______.
The phenomenon wherein, the ovary develops into a fruit without fertilisation is called______.
Parthenocarpy (parthenos-virgin, karpos-fruit) is the formation of seed less fruits without fertilization. The fruits developed from unfertilized ovary are called parthenocarpic fruits.
Other options are incorrect because:
